Why does my boiler drip?
A boiler leaking water needs the urgent attention of a heating engineer as it could lead to serious damage. Corroded pipes, high pressure and loose joints are all common causes of a boiler leaking water. If your boiler was only installed recently, the leak could be down to poor installation.
Should a boiler drop pressure?
What should my boiler’s pressure gauge read? When your boiler is switched off, the pressure gauge should read around 1 Bar – in the green zone on the gauge. When it is in operation (demanding heat/hot water), it’s pressure will increase slightly, then it should drop back down.
What does it mean when your boiler pressure keeps dropping?
If the expansion vessel is faulty, it normally means that it will not be able to handle the expanding hot water resulting in the pressure in the heating system rising rapidly and this water will be ejected through the pressure relief valve, once it goes beyond 3 bar in pressure.
Can a leak in a boiler cause pressure loss?
Whether you have an oil, system or combi boiler, pressure loss is usually directly related to a leak in boilers. We’ve already created a guide on why boilers leak and how to find leaks here. Most boilers operate at 1.0bar-1.5bar. But they can approach 3bar if there is a problem like a leak.
What should the pressure be on my boiler?
When your boiler is switched off, the pressure gauge should read around 1 Bar – in the green zone on the gauge. When it is in operation (demanding heat/hot water), it’s pressure will increase slightly, then it should drop back down. Need help?
How do you fix a low pressure boiler?
After diagnosing your problem, and getting it fixed, the final step in getting you low pressure boiler back up to the desired pressure is refilling the heating system with what is called a filling loop .

How is water pressure maintained in a boiler?
What is boiler water pressure? Your boiler heats cold water that flows around a circuit of pipes and radiators through your home. For it to work as efficiently as possible, your water pressure needs to be stable. Pressure in most modern combination boilers is maintained by a ‘filling loop’, which connects to your cold water pipe.
How can I check the pressure on my boiler?
How can I check my boiler pressure? Usually, on the front of your boiler, you’ll find a water pressure gauge. If you have a hydraulic pressure gauge, you’ll see low and high pressure indicated by red sections on the dial. The position set when the boiler was installed is sometimes shown by a red indicator needle.
